Project Labor Agreements. Building and construction trades workers are one of the hardest hit groups in the nationâs job crisis. Yet state lawmakers, backed by construction industry CEOs, want to cut the wages of those workers by eliminating prevailing wage laws and project labor agreements (PLAs) on public construction projects.
There are many algorithms to solve scrambled Rubik's Cubes. The maximum number of face turns needed to solve any instance of the Rubik's Cube is 20, and the maximum number of quarter turns is 26. These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. An algorithm that solves a cube in the minimum number of moves is known as God's algorithm. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of face turns.
This might be the biggest Rubik's Cube ever, but it takes muscle to solve it. We've seen the record-setting Rubik's Cube puzzle-solving by human and machine, but a new version of the cube hopes to set a different kind of record: the biggest, fully functional Rubik's Cube ever. That was Tony Fisher's goal when he set about creating his massive Rubik's Cube, which you have to walk around and push to move the colored squares into place. The cube is about five feet wide, weighs about 220 pounds and has an overall volume that's about 20,000 times larger than a normal Rubik's Cube. Fisher, a veteran puzzle maker, says it took several weeks between January and February 2016 to build it.
